Background / History

Yu Xiaogang's martial soul mutation left his cultivation permanently limited to the Soul Grandmaster realm. Unable to pursue renown through personal strength, he divided his ambitions between theory and fame through a gifted disciple, idolizing Tang Hao as the power he wished he possessed. 3 4

He published the Ten Core Competencies of Martial Soul and hoped that a genius would validate his work. Although some of its claims aided inexperienced civilian soul masters, prominent figures criticized it as poorly assembled common knowledge riddled with errors. 17 224

Yu Xiaogang reunited with Bibi Dong at Nuoding Academy after she told him that she had crippled her second martial soul to leave Martial Soul Hall and find him. He accepted this account immediately, blamed his own weakness for her suffering, and joined her in planning to destroy Martial Soul Hall and the Qian family. 39

Appearance

In his later years, Yu Xiaogang is a thin, elderly man with snow-white crew-cut hair. He wears a black-and-white student uniform. 310

• Short, white hair without visible black strands. 310
• Thin build and ordinary appearance. 310
• After his imprisonment, he temporarily walked with a visibly awkward, staggered gait. 222

Personality

Yu Xiaogang is intensely preoccupied with reputation. He seeks recognition as a great theorist and views talented disciples as proof that can establish his standing across the Spirit Master World. His desire for acclaim remains central even after his theories are publicly discredited. 3 74 224

He is opportunistic in his treatment of others. On encountering Tang San's Innate Full Soul Power and Blue Silver Grass, he immediately concluded that Tang San possessed Twin Martial Souls and set out to gain the boy's trust. 74 He also prioritizes the Blue Lightning Tyrant Dragon Clan's interests when they conflict with Tang San, Xiao Wu, or his other relationships. 149 205

Yu Xiaogang fears public disgrace more than physical danger. He abandoned Liu Erlong during her public confrontation, distanced himself from Shrek Academy when Martial Soul Hall threatened it, and hesitated to marry Bibi Dong because of the further damage it could do to his reputation. 172 204 226

Abilities & Skills

Luo Sanpao

Yu Xiaogang possesses the mutated martial soul Luo Sanpao and two yellow soul rings. 310

• His martial soul mutation prevents him from breaking through level 29. 39 310
• He attempted to use Luo Sanpao against Tang San, but Tang San disabled the martial soul before its attack could be released. 310
• His limited cultivation leaves him dependent on stronger allies and political connections in major conflicts. 117 310

Martial Soul Theory

Yu Xiaogang specializes in researching martial souls, soul rings, and cultivation paths.

• Published the Ten Core Competencies of Martial Soul in an effort to establish authority within the soul master world. 17
• Correctly proposed that beast martial souls could absorb soul rings from plant-type soul beasts, a conclusion later validated by Bibi Dong. 58
• Correctly identified Tang San's Blue Silver Grass and Innate Full Soul Power as evidence of a likely second martial soul. 74
• Misguided Tang San's Blue Silver Grass cultivation toward poison-type soul beasts, severely polluting the martial soul's development. 200 205
• Did not teach Tang San's hidden weapons, movement technique, or other Tang Sect abilities, despite Bibi Dong initially assuming he had done so. 109

Team Analysis and Mentorship

Yu Xiaogang serves as a mentor to academy teams and emphasizes resource management and tactical preparation.

• Explained the Elite Advanced Soul Master Academy Competition's rules to the Heaven Dou Second Team. 161
• Recommended preserving the team's strength against Martial Soul Hall because its healing- and food-type support far exceeded the Heaven Dou side's resources. 193
• Forfeited the Heaven Dou Royal Academy Second Team's opening match at the finals to avoid immediately provoking Martial Soul Hall and to protect clan interests. 192

Relationships

• Bibi Dong — Lover and former Holy Maiden of Martial Soul Hall. Yu Xiaogang believed her self-crippling sacrifice was made for him and supported her revenge against Martial Soul Hall; their relationship collapsed when he hesitated to publicly marry her. 39 225 226
• Tang San — Disciple whom Yu Xiaogang regarded as the proof of his theories and the foundation of his future fame. Their bond deteriorated after Tang San learned that Yu Xiaogang had misdirected his Blue Silver Grass cultivation and insulted Xiao Wu. 74 118 205
• Liu Erlong — Cousin and former fiancée. Yu Xiaogang publicly rejected her during the Heaven Dou qualifiers to avoid the scandal surrounding their relationship. 172
• Flender — Longtime friend and Shrek Academy associate. Yu Xiaogang entrusted Liu Erlong to him after rejecting her, then later disassociated himself from Shrek when it became politically dangerous. 172 204
• Yu Tianheng — Nephew and young master of the Blue Lightning Tyrant Dragon Clan. Yu Xiaogang favored Tianheng's clan interests and encouraged his relationship with Xiao Wu without disclosing her true identity. 149 151
• Yu Yuanzhen — Father and Blue Lightning Tyrant Dragon Clan leader. Yu Yuanzhen protected Yu Xiaogang from a Death Spider Emperor attack and was injured in the process. 203 237
• Hu Liena — Initially a potential subject for Yu Xiaogang's theoretical guidance; she later judged him unfavorably after observing his conduct toward Liu Erlong and Shrek Academy. 39 219

Story Role / Major Arcs

Tang San's Apprenticeship

At Nuoding Academy, Yu Xiaogang overhears Tang San's certificate details and becomes convinced that Blue Silver Grass paired with Innate Full Soul Power can only mean Twin Martial Souls. He uses his status to secure Tang San's admission, flatters Old Jack, and begins maneuvering Tang San toward apprenticeship. 74

Shrek and the Heaven Dou Second Team

Yu Xiaogang accompanies Tang San to Shrek Academy, later acting as a mentor for the Heaven Dou Royal Academy Second Team during the Elite Advanced Soul Master Academy Competition. He treats Tang San as both a disciple and the eventual validation of his theories. 80 117 161

Public Scandal and Imprisonment

Liu Erlong confronts Yu Xiaogang in public during the Heaven Dou qualifiers, exposing their cousin relationship and demanding an answer about their past. Yu Xiaogang rejects her and flees, causing widespread rumors involving himself, Liu Erlong, and Bibi Dong. 172 175

He later identifies the Spider Emperor Elder as a transformed Death Spider Emperor before Pope Hall. Martial Soul Hall discredits his accusation, forces him to kneel and apologize, and imprisons him. While incarcerated, he is tortured and humiliated before Yu Luomian retrieves him. 198 206 221 222

Break with Bibi Dong

After his release, Yu Xiaogang clings to the hope that Bibi Dong can still inherit the Rakshasa God position and restore his fortunes. When Bibi Dong proposes a public wedding, he delays and redirects her toward revenge and cultivation, leading her to recognize his self-interest and attempt to kill him. 225 226

Final Downfall

Following Bibi Dong's destruction of the Blue Lightning Tyrant Dragon Clan, Yu Xiaogang withdraws into seclusion, unable to seek revenge or advance beyond level 29. 310

Tang San later finds him while mortally wounded and attacks him in retaliation for Yu Xiaogang's humiliation of Xiao Wu. Tang San disables Luo Sanpao, pins Yu Xiaogang to a wall with daggers, and shatters his bones with the Mysterious Heaven Skill, leaving him alive to endure the injuries. 310
